Arterial injuries.

The authors review arterial injuries in 68 patients treated at Maisonneuve-Rosemont Hospital in Montreal between 1975 and 1982. Penetrating trauma caused 54.4% of these injuries, which consisted of either laceration or intimal tear with thrombosis. Arterial injuries of the extremities were predominant (58.8%). Associated injuries were frequent. Surgical repair was effected in 60 patients. End-to-end anastomosis, angioplasty and venous or prosthetic bypass grafting were the techniques used. Postoperative complications occurred in 37% of the patients. Overall mortality was 19% and was related mainly to aortic injury. The amputation rate for arterial injuries of the extremities was 15%. Prompt recognition and treatment of arterial injuries are important in order to achieve the best results.
